Apologies, but I’m not quite sure how to troubleshoot there. This is just a third-party plugin. I’m not totally versed with the ins and outs of how it works under the hood. It’s always worked for me the way I show in the video and haven’t every personally experienced the issue you’re facing.
From looking at the demo, is there a widget somewhere you can’t figure out how to duplicate? Let me know, and I’d be glad to just tell you what widget I used in the demo on whatever page or section.
